I am having some problems and need some advice. My truck has been running pretty poorly the last 2 months. It started off stalling when I came to a stop, then it would start right up again. It also started sputtering when the engine was loaded and having some black smoke when cold (fouling out my spark plugs pretty bad).
Replaced the fuel pump and rebuilt the carb. Ran great for 2 days, now it's doing it again. I checked timing, points, coil etc...its getting plenty of spark. What did I miss?
